Roller bearing for e.g. motor, has rolling body, inner ring and outer ring exhibiting circular magnetization with alternative polarized sections, where rings effect forced rotation of another rolling body during rotation of inner ring

摘要

The bearing (1) has a rolling body (4) i.e. cylindrical roller, and an inner ring (2) with a bearing surface (11), on which the rolling body with rolling surfaces is rolled. Another rolling body (4`) is provided with circular magnetization with alternative polarized sections (6-9). The inner ring and an outer ring (3) exhibit a corresponding magnetization with circular and alternative polarized sections (13-16). The inner and outer rings effect forced rotation of the rolling body (4`) during rotation of the inner ring.
